Do not leave a battery, lead acid or lithium in a discharged state or the cells will be permanently damaged. Charge immediately if this happens.

Most of the time, it means you need to charge the battery as it is at a low charge level but it could mean several things. First thing you need to do it put a voltmeter on the battery, if the voltage is less than 13.28V, the LED light will flash to let you know to charge the battery. If the voltage is above 13.28V and flashing, then you could have a weak cell /a cell out of balance/or defective cell and you need to contact EarthX for a warranty coverage if it is less than 2 years old. The LED will also flash if the voltage is too high, above 14.6V. If the light is solid and remains on for more than 10 minutes, then it is an indication of a BMS electronics problem and contact EarthX.
|LED Light||Voltage||Possible Cause||Recommended Action|
|Slow Flashing (5s on/5s off)||Less than 12.8V||Battery over-discharged (due to faulty charging system)||Charge battery. Once charged, the light will stop flashing.|
|Slow Flashing (5s on/5s off)||Less than 13.2V||Weak or failing cell||Charge battery. If voltage drops below 13.2V within a few days, discontinue use.|
|Slow Flashing (5s on/5s off)
(> 1 hour time period)
|13.2V-14.6V||Weak or failing cell||Discontinue use. If in flight, this is not an immediate issue unless it is in conjunction with a charging system failure.|
|Slow Flashing (5s on/5s off)||Greater than 15.2V||Over-charging (due to faulty charging system)||If in flight, shutoff charging system immediately. Aircraft over-voltage protection is required if alternator charging system is greater than 20 amps (i.e. over voltage crowbar circuit)|
(5s on/5s off) (< 30 min. time period)
|13.2V – 14.6V||Cell to cell charge levels are not balanced||May come on briefly during periods of high current charging until the cells are automatically balanced. Try charging with a plugin charger, like an Optimate Lithium charger.|
|Solid Light||Any voltage||BMS electronic issue||Discontinue use. If in flight, this is not an immediate issue unless it is in conjunction with a charging system failure.|
|Solid Light that turns off after 3 minutes||Any voltage||Short Circuit protection was activated||Nothing needs to be done.|
|Short Flashing (2s on/2s off)||Any voltage||High battery temperature (> 65°C / 150°F)||Let battery cool down prior to cranking or charging.|
No, the amount of current hand held starters can put out can be damaging to the EarthX batteries and we do not recommend nor warranty cover the batteries in this type application.
All batteries have a life span, even if left in the box and never used. Time is a factor even if properly cared for, eventually, all batteries die. An EarthX battery is rated for 5-8 years if properly maintained, which means it is not left in a discharged state (below 13.28V); used in a properly functioning charging system; used with a proper charger; not shorted; and proper temperature ratings have been followed. All batteries will self discharge and depending on the amp hour of the battery, and it’s temperature it is stored in, the level of discharge and amount of time are variable. Always keep your lithium battery above 13.28V for longest life.
The ETZ14C has 330CCA, 690PCA; weighs 2.5 pounds; has 6.8Ah capacity and has the battery management system minus over discharge protection and excessive cranking protection so it will not cut off in cold weather starts with a 1 year warranty. This battery was designed for high cranking amps in the cold. The dimensions are 150mm x 86mm x 115mm or 5.9″ x 3.4″ x 4.5″. ( L x W X H)The cost is $249.

The ETX36C and the ETZ14C are both the exact same physical size but it is smaller than the ETX36D.
The ETZ5G has 140CCA, 240PCA; weighs .9 pounds; has 3.4Ah capacity and has the battery management system minus over discharge protection and excessive cranking protection so it will not cut off in cold weather starts with a 1 year warranty. This battery was designed for high cranking amps in the cold. The cost is $139.
If a battery does not seem to charge or perform as well as it once did, it may be for one or more of the following issues:
- There may be a problem with the charging system. While the charging system is in operation, it will begin putting out approximately 13.8 -14.6volts.
- The vehicle electrical system may have a short circuit or current drain
- The terminals on the battery are not properly tightened
- There may be a problem with the battery itself so if you have verified that it is not a parasitic drain, and the battery is losing power within 1-7 days, then contact EarthX. Do not continue to attempt to charge or use a battery that will not hold a charge as it might indicated cell failure and continued use can cause cell rupture, smoke and even fire.
- Never leave the battery or the vehicle unattended when recharging it.
- When charging a battery, place it on a non-flammable, and remove any flammable items nearby.
- Unplug chargers from the battery or vehicle always after the battery reaches full charge.
- Disconnect chargers when not in use.
